Emergent properties of plant hydraulic architecture: From root cells to cavitating stems and land surface models

Hydrological processes in plants are multi-scale, involving sub-cellular elements such as aquaporins as well as long distance transport in xylem tissues vulnerable to cavitation in diverse root and shoot architectures. Their integration in dynamic vegetation models faces a major challenge: the avoidance of over-complexification while retaining the essential features of hydrological phenomena across scales
